Description

SONDE POUR LE TRAITEMENT HAUTE FRÉQUENCE DE LA PEAU PROBE FOR HIGH FREQUENCY SKIN TREATMENT
DOMAINE TECHNIQUETECHNICAL AREA
L'invention se rapporte au traitement de la peau par des moyens électriques à haute fréquence associés ou non à une source de rayonnement électromagnétique laser, en particulier pour l'épilation dite "définitive" ou "longue durée" ainsi que pour la repousse des cheveux.The invention relates to the treatment of the skin by high frequency electrical means, whether or not associated with a source of laser electromagnetic radiation, in particular for so-called "permanent" or "long-term" hair removal as well as for hair regrowth. .
ETAT DE LA TECHNIQUESTATE OF THE ART
WO 93/04636 décrit un procédé basé sur la constatation qu'en mélangeant un gel conducteur de type usuel pour l'application de sondes à ultrasons contre la peau avec un produit traitant, par exemple une lotion à effet d'atrophie sur les racines des poils, il était possible, par induction transcutanée à haute fréquence, de faire pénétrer le produit traitant dans les follicules pileux (pores) et la tige des poils, et ainsi d'effectuer un traitement.WO 93/04636 describes a method based on the observation that by mixing a conductive gel of the usual type for the application of ultrasound probes against the skin with a treating product, for example a lotion with an atrophy effect on the roots of hairs, it was possible, by high frequency transcutaneous induction, to penetrate the treating product into the hair follicles (pores) and the hair shaft, and thus to carry out a treatment.
Ce procédé permet ainsi d'effectuer un traitement, notamment cosmétique, de la peau, par exemple en vue d'une épilation longue durée, voire définitive, et permet de surcroît une application ponctuelle et efficace au niveau des follicules, sans intervention manuelle délicate.This process thus makes it possible to carry out a treatment, in particular cosmetic treatment, of the skin, for example with a view to long-term or even permanent depilation, and moreover allows a punctual and effective application to the follicles, without delicate manual intervention.
Pour la mise en oeuvre du procédé, WO 93/04636 décrit en outre un appareil comprenant un organe maniable de contact avec la peau ayant un corps non-conducteur pourvu d'une surface d'appui destinée à être appliquée sur la peau. Cette surface comporte une pluralité de points conducteurs d'émission électromagnétique distincts formés par exemple par des parties exposées de spires d'un solénoïde noyé, dans le corps de l'organe de contact. Ces points débouchent par des orifices dans cette surface, de préférence en retrait par rapport à celle-ci, de manière que, en cours d'utilisation de l'appareil, ils puissent contacter du gel conducteur appliqué sur la peau. Ces points d'émission distincts émettent un flux d'énergie électromagnétique à haute fréquence, avantageusement un courant émetteur pur, fourni par un circuit électrique oscillant haute fréquence de puissance.For the implementation of the method, WO 93/04636 further describes an apparatus comprising a handy member for contact with the skin having a non-conductive body provided with a bearing surface intended to be applied to the skin. This surface comprises a plurality of separate electromagnetic emission conductive points formed for example by exposed parts of turns of a submerged solenoid, in the body of the contact member. These points open out through orifices in this surface, preferably set back from the latter, so that, during use of the device, they can contact conductive gel applied to the skin. These Separate emission points emit a flow of high frequency electromagnetic energy, advantageously a pure emitting current, supplied by a high frequency oscillating electric power circuit.
Pour la mise en oeuvre du même procédé, WO 96/03928 décrit une sonde flexible susceptible de se conformer à la partie du corps contre laquelle elle est appliquée, comportant des parties non-conductrices inférieure/interne et supérieure/externe. Au moins la partie inférieure/ interne est dotée de cavités présentant une pluralité de points conducteurs d'émission électromagnétique distincts formés par des parties de spires d'une bobine disposés en retrait par rapport à la surface inférieure/interne de la sonde.For the implementation of the same method, WO 96/03928 describes a flexible probe capable of conforming to the part of the body against which it is applied, comprising lower / internal and upper / external non-conductive parts. At least the lower / internal part is provided with cavities having a plurality of distinct electromagnetic emission conductive points formed by parts of turns of a coil arranged recessed with respect to the lower / internal surface of the probe.
Dans une autre évolution de la technique, le brevet français 2 589 067 décrit un procédé et un dispositif basés sur la constatation qu'un champ électrique appliqué à la peau en combinaison avec un rayonnement électromagnétique laser permet de modifier les propriétés d'absorption de ladite peau.In another development of the technique, French patent 2,589,067 describes a method and a device based on the observation that an electric field applied to the skin in combination with laser electromagnetic radiation makes it possible to modify the absorption properties of said skin.
EXPOSE DE L ' INVENTIONSTATEMENT OF THE INVENTION
La présente invention a pour obj et une sonde pour l ' application d ' un f lux d ' énergie électromagnétique haute fréquence sur la peau ( utilisable notamment dans les procédés décrits dans WO 93 / 04636 et le brevet français 2 589 067 , ou autre procédé nécessitant l ' application d ' un gel conducteur) , cette sonde présentant une surface d ' appui non-conductrice destinée à être appliquée sur la peau et présentant dans son épai s seur au mo ins une cavité débouchant par un orif ice dans la surface d ' appui ainsi qu ' au moins un élément inducteur de champ électromagnétique destiné à émettre un champ électromagnétique à travers ladite cavité et son orifice .The object of the present invention is a probe for the application of a f lux of high frequency electromagnetic energy to the skin (usable in particular in the methods described in WO 93/04466 and French patent 2,589,067, or other method requiring the application of a conductive gel), this probe having a non-conductive support surface intended to be applied to the skin and having in its thickness at least a cavity opening out through an orifice ice in the surface of 'support as well as at least one electromagnetic field inducing element intended to emit an electromagnetic field through said cavity and its orifice.
La sonde selon 1 ' invention est caractérisée en ce que ledit élément inducteur se trouve dans son épaisseur à un niveau intermédiaire de la profondeur de ladite cavité , cet élément inducteur s ' étendant au moins partiellement autour et/ou au voisinage de la paroi de ladite cavité.The probe according to the invention is characterized in that said inducing element is in its thickness at an intermediate level from the depth of said cavity, this inductor element extending at least partially around and / or in the vicinity of the wall of said cavity.
D'autres caractéristiques de la sonde selon l'invention sont exposés dans les revendications 2-15. L'invention concerne également l'utilisation de cette sonde pour des traitements cosmétiques de la peau, comme exposé dans les revendications 16-18, et un procédé de traitement cosmétique de la peau selon les revendications 19-23.Other characteristics of the probe according to the invention are set out in claims 2-15. The invention also relates to the use of this probe for cosmetic treatments of the skin, as set out in claims 16-18, and to a method of cosmetic treatment of the skin according to claims 19-23.
Lors de l'utilisation de la sonde, on applique par exemple un mélange de gel/produit traitant sur la surface de la peau à traiter et/ou dans les cavités de la surface d'appui de la sonde de manière que ce mélange serve d'interface conducteur entre la surface d'appui de la sonde flexible et la peau.When using the probe, a mixture of gel / treating product is applied, for example, to the surface of the skin to be treated and / or to the cavities in the support surface of the probe so that this mixture serves conductive interface between the support surface of the flexible probe and the skin.
La sonde selon 1 ' invention présente divers avantages . Par exemple, la disposition intermédiaire de l'élément inducteur de champ magnétique permet d'agrandir la cavité et/ou de la rendre traversante dans l'épaisseur de la sonde, de manière à pouvoir installer une source d'émission électromagnétique laser dans l'épaisseur ou sur la face supérieure/externe de la sonde. Cet arrangement permet l'application simultanée aisée d'un champ électromagnétique et d'un rayonnement électromagnétique laser sur la peau, comme décrit dans le brevet français 2 589 067. En outre, la disposition intermédiaire de l'élément inducteur de champ magnétique permet une fabrication aisée des sondes par perforation. Par ailleurs, la disposition des éléments inducteurs de champ magnétique au moins partiellement autour et/ou au voisinage de la paroi des cavités permet de les disposer en couches successives, ce qui permet de multiplier le nombre de points d'émission de champ électromagnétique dans chaque cavité. Cette disposition permet en outre d'augmenter la quantité de mélange gel/produit traitant dans les cavités soumis au champ électromagnétique produit par les multiples points d'émission. Ceci augmente l'intensité du champ électromagnétique appliqué au mélange gel/produit et à la peau, et ainsi le pouvoir traitant des produits appliqués. - A -The probe according to the invention has various advantages. For example, the intermediate arrangement of the magnetic field inducing element makes it possible to enlarge the cavity and / or make it pass through in the thickness of the probe, so as to be able to install a source of laser electromagnetic emission in the thickness or on the upper / outer face of the probe. This arrangement allows easy simultaneous application of an electromagnetic field and laser electromagnetic radiation on the skin, as described in French patent 2,589,067. In addition, the intermediate arrangement of the magnetic field inducing element allows a easy manufacturing of perforation probes. Furthermore, the arrangement of the magnetic field inducing elements at least partially around and / or in the vicinity of the wall of the cavities makes it possible to arrange them in successive layers, which makes it possible to multiply the number of electromagnetic field emission points in each cavity. This arrangement also makes it possible to increase the quantity of gel / treating product mixture in the cavities subjected to the electromagnetic field produced by the multiple emission points. This increases the intensity of the electromagnetic field applied to the gel / product mixture and to the skin, and thus the processing power of the products applied. - AT -
Les éléments inducteurs de champ électromagnétique sont par exemple constitués par des spires aplaties, ou par un réseau ou une grille constituée de matériau conducteur. Le matériau conducteur est de préférence une feuille conductrice en résine de silicone, un tissu de fibres conductrices telles des fibres de carbone, ou un textile non tissé dont les fibres sont conductrices.The electromagnetic field inducing elements are for example constituted by flattened turns, or by a network or a grid made of conductive material. The conductive material is preferably a conductive sheet of silicone resin, a fabric of conductive fibers such as carbon fibers, or a non-woven fabric whose fibers are conductive.
Dans les formes d'exécution comprenant une source de rayonnement électromagnétique laser, celle-ci peut être constituée soit par une diode d'émission laser logée dans l'épaisseur ou sur la face supérieure/externe de la sonde, soit par une fibre optique reliée à une source laser externe à la sonde. Dans ces mêmes formes d'exécution, un arrangement possible est de disposer les cavités pratiquées dans la surface d'appui en réseau ou en lignes formant des figures géométriques diverses, et de disposer les sources laser de manière régulière dans ledit réseau ou lesdites lignes.In the embodiments comprising a source of laser electromagnetic radiation, this can be constituted either by a laser emission diode housed in the thickness or on the upper / external face of the probe, or by an optical fiber connected to a laser source external to the probe. In these same embodiments, a possible arrangement is to arrange the cavities formed in the bearing surface in a network or in lines forming various geometric figures, and to arrange the laser sources regularly in said network or said lines.
Si désiré, l'application du flux d'énergie électromagnétique peut suivre un programme déterminé par les moyens générateurs d'impulsions électriques et les moyens d'excitation de sources laser, par exemple en alternant les deux types de rayonnement électromagnétique et/ou en en variant l'intensité.If desired, the application of the electromagnetic energy flow can follow a program determined by the means generating electrical pulses and the means for exciting laser sources, for example by alternating the two types of electromagnetic radiation and / or by varying the intensity.
La sonde selon l'invention peut être utilisée, en combinaison avec un gel traitant, pour le traitement cosmétique de la peau, notamment l'épilation longue durée, la calvitie, la couperose et les varicosités veineuses et capillaires.The probe according to the invention can be used, in combination with a treating gel, for the cosmetic treatment of the skin, in particular long-term hair removal, baldness, rosacea and varicose veins and capillaries.

Ces cavités 6 ont typiquement un diamètre entre 3mm et 6mm tandis que la cavité 4 d'émission de rayonnement laser a typiquement un diamètre entre 6mm et 10mm.The probe shown in Figures 1 and 2 comprises a handy contact member 1 of elongated shape, connected, at one of its ends, to a current supply 2 and which has at its other end a circular support surface 14. The current supply 2 feeds an electromagnetic field inducing element 5 disposed back from the contact surface, emitting through cavities 6, six in number in this example, opening into the bearing surface 14. The element electromagnetic field inductor 5 is located at an intermediate level of the depth of the cavities 6, this inductive element extending at least partially around and / or in the vicinity of the wall 7 of the cavities 6. A source of laser electromagnetic radiation 8 emits at through an additional cavity 4 located in the axis of the member 1, opening into the bearing surface 14 at the center of the cavities 6. These cavities 6 typically have a diameter between 3mm and 6mm while the cavity 4 for emitting laser radiation typically has a diameter between 6mm and 10mm.
La forme d'exécution représentée aux Figures 3 et 4 est une sonde flexible 9 comprenant plusieurs (en l'espèce, quatre) couches de caoutchouc flexible entre lesquelles sont intercalées plusieurs (en l'espèce trois) éléments inducteurs 5 occupant la quasi totalité de la sonde flexible, excepté son pourtour non-conducteur 10. Les éléments inducteurs 5 sont disposés en plusieurs couches connectées électriquement entre elles par des connections 11, et reliées à une amenée de courant non-representée . On distingue sur la Figure 4 deux éléments inducteurs 5 ' situés à des niveaux intermédiaires de la profondeur des cavités 6, ainsi qu'un élément inducteur 5" optionnel situé au fond des cavités 6. Chaque élément inducteur 5 est par exemple constitué d'un tissu de fibres de carbone tissé 12 présentant des perforations 13. La sonde flexible 9 présente une face inférieure/interne constituant la surface d'appui 14, et une face supérieure/externe 15. Les cavités 6 sont situées dans l'épaisseur de la feuille en matériau flexible et débouchent dans la surface inférieure/interne 14 par des orifices 3. En variante, représentées en pointillé sur la Figure 4, les cavités 6 sont perforantes et traversantes, ce qui facilite la fabrication.The embodiment shown in Figures 3 and 4 is a flexible probe 9 comprising several (in this case, four) layers of flexible rubber between which are interposed several (in this case three) inducing elements 5 occupying almost all of the flexible probe, except its non-conductive periphery 10. The inductor elements 5 are arranged in several layers electrically connected to each other by connections 11, and connected to a power supply not shown. We distinguish in Figure 4 two inductor elements 5 'located at intermediate levels of the depth of the cavities 6, as well as an optional inductor element 5 "located at the bottom of the cavities 6. Each inductor element 5 consists for example of a woven carbon fiber fabric 12 having perforations 13. The flexible probe 9 has a lower / internal face constituting the bearing surface 14, and an upper / external face 15. The cavities 6 are located in the thickness of the sheet made of flexible material and open into the lower / internal surface 14 through orifices 3. As a variant, shown in dotted lines in FIG. 4, the cavities 6 are perforating and traversing, which facilitates manufacture.
La forme d'exécution représentée aux Figures 5 et 6 est une sonde flexible 9 comportant des sources d'émission laser 8. Comme avant, la sonde se présente sous forme d' une feuille flexible pourvue d'une face inférieure/interne formant la surface d'appui 14, et une face supérieure/ externe 15. La sonde comporte d'une part des cavités borgnes 6 disposées en réseau formant des figures géométriques, par exemple selon une disposition circulaire, et d'autre part des cavités traversantes additionnelles 4 disposées de manière régulière dans ledit réseau, permettant le passage du rayonnement électromagnétique laser 16 émis par la source 8. Les cavités 6 sont réparties autour des cavités traversantes 4 de manière à obtenir une répartition uniforme du rayonnement électromagnétique induit et du rayonnement laser. La sonde 9 est reliée par une amenée de courant 2 à des moyens générateurs d'impulsions électriques reliées aux éléments inducteurs 5, ainsi qu'à des moyens d'excitation des sources laser 8. Des exemples de ces deux types de moyens sont décrits par exemple dans le brevet français 2 589 067. En outre, avantageusement, la source laser comporte une lentille permettant la défocalisation du faisceau laser.The embodiment shown in Figures 5 and 6 is a flexible probe 9 comprising laser emission sources 8. As before, the probe is in the form of a flexible sheet provided with a lower / internal face forming the surface support 14, and an upper / outer face 15. The probe comprises on the one hand blind cavities 6 arranged in a network forming geometric figures, for example in a circular arrangement, and on the other hand additional through cavities 4 arranged in a regular manner in said network, allowing the passage of the electromagnetic laser radiation 16 emitted by the source 8. The cavities 6 are distributed around the through cavities 4 so as to obtain a uniform distribution of the induced electromagnetic radiation and the laser radiation. The probe 9 is connected by a current supply 2 to means generating electrical pulses connected to the inductor elements 5, as well as to means for exciting laser sources 8. Examples of these two types of means are described for example in French patent 2 589 067. In addition, advantageously, the laser source comprises a lens allowing the defocusing of the laser beam.
Si désiré, les différentes exécutions de la sonde 9 comportent en outre un interrupteur agencé de manière à activer l'application du flux d'énergie électromagnétique haute fréquence et l'excitation des sources laser lorsque la sonde est mise en contact avec la peau et/ou le gel. Cette caractéristique augmente la sécurité d'utilisation de la sonde, notamment dans les formes d'exécution comportant une ou plusieurs sources électromagnétiques laser. L'interrupteur, relié aux moyens générateurs d'impulsions électriques et aux moyens d'excitation de sources laser grâce à l'amenée de courant 2, peut être mécanique, optoélectronique, à impedance/capacitance de la peau et/ou du gel , ou de tout autre type connu de 1 ' homme de 1 ' art . Dans une variante, cet interrupteur est couplé avec un dispositif permettant de temporiser l'enclenchement ou le déclenchement de l'application du flux d'énergie électromagnétique lorsque la sonde est mise en contact avec la peau et/ou le gel, ou lorsqu'elle en est retirée.If desired, the different embodiments of the probe 9 also include a switch arranged so as to activate the application of the high frequency electromagnetic energy flow and the excitation of the laser sources when the probe is brought into contact with the skin and / or frost. This characteristic increases the safety of use of the probe, in particular in embodiments comprising one or more electromagnetic laser sources. The switch, connected to the means for generating electrical pulses and to the means for exciting laser sources by means of the current supply 2, may be mechanical, optoelectronic, with impedance / capacitance of the skin and / or of the gel, or of any other type known to those skilled in the art. In a variant, this switch is coupled with a device making it possible to delay the switching on or off of the application of the flow of electromagnetic energy when the probe is brought into contact with the skin and / or the gel, or when it is withdrawn from it.
Typiquement, les impulsions créant le champ électromagnétique sont des impulsions d'activation statique ayant des durées allant de 1 microseconde à 1 seconde, et ayant des fréquences de modulation à rapport constant de 5Hz à 1000Hz. Le rayonnement laser a normalement une énergie de 0.5 mW à 150 mW. Cependant, on peut utiliser des énergies plus élevées, de 500 mW et davantage, dans la mesure où le faisceau est défocalisé par une lentille afin de créer un champ de plus grande surface.Typically, the pulses creating the electromagnetic field are static activation pulses having durations ranging from 1 microsecond to 1 second, and having modulation frequencies with constant ratio of 5Hz to 1000Hz. The laser radiation normally has an energy of 0.5 mW to 150 mW. However, higher energies of 500 mW and more can be used, as long as the beam is defocused by a lens in order to create a field of larger area.
Le gel chargé utilisé pour le procédé de traitement est de préférence composé d'un gel conducteur non-polymérisable d'un type usuel pour le couplage ultrasonique d'électrodes sur la peau, en mélange avec un produit traitant. Le gel a un pH neutre et est, par exemple, à base gélifiante composée de t r i thanolaminepr opy 1 ène glycol- carboxyvinylique . La composition du produit traitant dépend de l'action souhaitée. Pour une action dépilatoire, on peut choisir un produit à effet d'atrophie progressif de la racine du poil, par exemple une lotion post-épilatoire du type utilisé d'habitude immédiatement après une épilation à la cire, ainsi que les jours suivants. De telles lotions comportent des extraits de plantes, des huiles essentielles, de l'eau déminéralisée et éventuellement d'autres composants, par exemple des polyoxyéthylènes . Ces produits, connus parfois sous la dénomination "modérateur de la repousse des poils", sont sans danger d'utilisation toxique ou autre .The charged gel used for the treatment process is preferably composed of a non-polymerizable conductive gel of the usual type for the ultrasonic coupling of electrodes on the skin, mixed with a treating product. The gel has a neutral pH and is, for example, gelling base composed of tri thanolaminepr opy 1 ene glycol-carboxyvinyl. The composition of the treating product depends on the desired action. For a depilatory action, one can choose a product with a progressive atrophy effect of the hair root, for example a post-depilatory lotion of the type usually used immediately after waxing, as well as on the following days. Such lotions include plant extracts, essential oils, demineralized water and possibly other components, for example polyoxyethylenes. These products, sometimes known under the name "moderator of hair regrowth", are without danger of toxic or other use.
Pour un traitement de la calvitie, on peut mélanger le gel avec, par exemple, du minoxydil, ou tout autre produit favorisant la repousse des cheveux. Un mélange de 50:50 vol% de gel et de minoxydil a donné des résultats satisfaisants.For a treatment of baldness, one can mix the gel with, for example, minoxydil, or any other product promoting hair regrowth. A mixture of 50:50 vol% gel and minoxydil has given satisfactory results.
Afin de ne pas compromettre les propriétés conductrices du gel, la part du produit actif ou traitant n'excédera en général pas 50%, usuellement moins de 25%, en poids du gel (% en poids = % en volume) . On peut ajouter de l'alcool, du chlorure de sodium et/ou d'autres substances pour améliorer la conductivité du produit, et/ou comme agents conservateurs .In order not to compromise the conductive properties of the gel, the proportion of the active or treating product will generally not exceed 50%, usually less than 25%, by weight of the gel (% by weight =% by volume). Alcohol, sodium chloride and / or other substances can be added to improve the conductivity of the product, and / or as preservatives.
Des tests ont démontré que l'application d'une énergie à haute fréquence sur le produit traitant seul ou sur le gel seul n'aboutit à aucun effet spécial, tandis qu'en mélange, on obtient une bonne pénétration du produit traitant entraîné par la solution conductrice provenant du gel. Il semble que la conduction de l'énergie électromagnétique et électrique suit le chemin de moindre résistance offert par le mélange du gel et de la lotion conductrice appliqué à la surface de la peau, et ensuite autour de la racine du poil ou du cheveu par la seule lotion conductrice qui pénètre dans le follicule pileux et la tige du poil. Le gel permet un dégagement progressif de la lotion active et sa pénétration, sous l'action conjuguée des champs électromagnétique et électrique. Dans les formes d'exécution comportant des couches successives d'éléments inducteurs, la multiplication des points d'émission de champ électromagnétique et la quantité plus importante de mélange gel/produit traitant présent dans les cavités permet une pénétration plus complète du produit traitant. Cet effet est en outre renforcé par l'adjonction d'un rayonnement électromagnétique laser.Tests have shown that the application of high-frequency energy to the treatment product alone or to the gel alone has no special effect, while in mixing, good treatment product penetration is obtained. conductive solution from the gel. It seems that the conduction of electromagnetic and electrical energy follows the path of least resistance offered by the mixture of the gel and the conductive lotion applied to the surface of the skin, and then around the root of the hair or the hair by the the only conductive lotion that penetrates the hair follicle and the hair shaft. The gel allows a gradual release of the active lotion and its penetration, under the combined action of the electromagnetic and electric fields. In the embodiments comprising successive layers of inducing elements, the multiplication of the electromagnetic field emission points and the greater quantity of gel / treating product mixture present in the cavities allows a more complete penetration of the treating product. This effect is further enhanced by the addition of electromagnetic laser radiation.
Comme illustré aux Figures 1 et 6, les éléments inducteurs de champ électromagnétique 5 entourent également les cavités traversantes 4, et forment une partie des parois de ces cavités. Ainsi, le gel dans ces cavités 4 est à la fois ionisée par l'action du champ électromagnétique et traversée par le rayon laser. Cette action simultanée produit un effet synergique, et favorise une longue durée d'action sans danger sur la peau.As illustrated in Figures 1 and 6, the electromagnetic field inducing elements 5 also surround the through cavities 4, and form part of the walls of these cavities. Thus, the gel in these cavities 4 is both ionized by the action of the electromagnetic field and traversed by the laser beam. This simultaneous action produces a synergistic effect, and promotes a long duration of safe action on the skin.
Avantageusement, la sonde selon l'invention fait partie d'un set comportant: une ou plusieurs sondes rigides selon l'invention adaptées pour le traitement de différentes parties du corps, chaque sonde rigide comportant une source laser (voir la Figure 1) ou plusieurs sources laser disposées dans un organe rigide maniable, par exemple trois sources dans des cavités 4 disposées symmétriquement autour de l'axe de l'organe; plusieurs sondes flexibles de dimensions différentes, avec source laser (par exemple selon les Figures 5 et 6) ou sans source laser (par exemple, selon les Figures 3 et 4, ou tel que décrit dans WO 96/03928); et au moins un embout porte aiguille pour la microthermolyse ou 1 ' électrocoagulation. Toutes ces sondes et embouts sont interchangeables et peuvent être commandés par une unité centrale, permettant une très grande variété de traitements. Advantageously, the probe according to the invention is part of a set comprising: one or more rigid probes according to the invention adapted for the treatment of different parts of the body, each rigid probe comprising a laser source (see Figure 1) or more laser sources arranged in a handy rigid member, for example three sources in cavities 4 arranged symmetrically around the axis of the member; several flexible probes of different dimensions, with laser source (for example according to Figures 5 and 6) or without laser source (for example, according to Figures 3 and 4, or as described in WO 96/03928); and at least one needle holder tip for microthermolysis or electrocoagulation. All these probes and tips are interchangeable and can be controlled by a central unit, allowing a very wide variety of treatments.
